Description
Despite the general applicability of classical Ekman theory, individual observations of wind veering in the planetary boundary layer seldom exhibit the typical spiral turning with height. This study attempts to assess the reasons for these deviations from theory which occur not only as large fluctuations in time but also as significant differences in mean profiles from one location to another.

Description
Two well documented cases of tradewind disturbances are studied. One disturbance developed into Hurricane Carla (1961) while the other failed to intensify. Initially the two cases appeared to be very similar but on closer inspection the flow patterns in which the disturbances were embedded proved to have significant differences. This paper describes these differences.

Description
The geostrophic system of equations with both the effects of orography and heat contrast corresponding to land-sea distribution is integrated with respect to time by using the spectral method. The computed results show the appearance of reasonable blocking situation and a corresponding double jet stream in the latitudinal distribution of the zonally averaged zonal wind.

Description
The present study is designed to provide both a method whereby the details of the nonlinear exchange process which occurs in the atmosphere may be considered in a simplified form, and also to indicate from some calculations the complexity of those exchanges.

Description
A generalization of the two-dimensional spectral forecast equations is suggested, whereby the atmospheric flow field in horizontal and vertical directions is represented in terms of orthogonal functions, which are eigenfunctions of certain differential operators in the three-dimensional equations. The technique is applied to the quasi-geostrophic potential vorticity equation.

Description
The structure of hail-producing and no hail-producing atmosphere is studied by examining rawinsondes launched at New Raymer, Colorado, in the summer of 1967. It is found through examination of mean soundings and the convective condensation level and level of free convection that an ample low-level moisture supply is important for hailstorms to form.
